Nathan Cleverly's next opponent Ryan Coyne has claimed that their WBO light-heavyweight title fight is on the verge of being scrapped.

The bout, which was scheduled to take place in Los Angeles on November 10, has apparently been downed by a legal dispute between Don King, Coyne's former promoter, and Frank Warren, who looks after Cleverly.

"I am sorry to toss a monkey wrench in things, but my fight with Nathan Cleverly is not going to happen," Coyne told World Boxing News.

"I personally am 100% ready to go forward with this fight and I can't wait to oppose Nathan Cleverly next month, but Don threatened the WBO and Frank Warren with a lawsuit and that seems to be that. It is a dreadful situation that has cost me dearly."

Cleverly was looking to make the fourth defence of his belt, which he landed in May 2011, against Coyne.
